Public bus transport demand elasticities in India

Deb, Kaushik ; Filippini, Massimo

In: Journal of transport economics and policy, 2013, vol. 47, no. 3, p. 419-436

A number of static and dynamic specifications of a log-linear demand function for public transport are estimated using aggregate panel data for twenty-two Indian states over the period 1990 to 2001. In all cases, transit demand is significant and inelastic with respect to the fare. Service quality, approximated by the density of the coverage of the transport service, seems to be an important...

Regional consumption of antibiotics : a demand system approach

Filippini, Massimo ; Masiero, Giuliano ; Moschetti, Karine

In: Economic Modelling, 2009, vol. 26, no. 6, p. 1389-1397

Through this paper, we have attempted to model the demand for different classes of antibiotics used for respiratory infections in outpatient care in Switzerland using a spatial version of the linear approximate Almost Ideal Demand System (AIDS) model. This model takes spatial dependency into account by means of spatial lags of antibiotic budget shares. We control for the health status of patients...

Characteristics of demand for antibiotics in primary care : an almost ideal demand system approach

Filippini, Massimo ; Masiero, Giuliano ; Moschetti, Karine

We model demand for different classes of antibiotics used for respiratory infections in outpatient care using a linear approximate almost ideal demand system approach. We compute elasticities to socioeconomic determinants of consumption and own- and cross- price elasticities between different groups of antibiotics. We find significant elasticities between newer/more expensive generations and...
